A riding greensmower clean-up pass speed control system reduces the maximum ground speed if a clean-up pass control is actuated. The reduced maximum ground speed is adjustable using a display. The maximum ground speed is increased to the previous ground speed each time the plurality of grass cutting reels are raised after the clean-up pass.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.

The invention relates to an apparatus (10), preferably an autonomous robot apparatus, for mowing grass. The apparatus (10) has a plurality of cutting devices (20) for mowing the grass. The apparatus (10) has a plurality of carrying arms (22) which are arranged offset with respect to one another with regard to the transverse axis of the apparatus (10), and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices (20). The apparatus (10) has a plurality of supporting elements (24) which support in each case one of the plurality of carrying arms (22) on an underlying surface, and are arranged in front of the respective cutting device (20) with regard to a forward moving direction (V) of the apparatus (10). The apparatus (10) can have the advantage that the leading supporting elements (24) do not push any cuttings in front of them, and a risk of the apparatus (10) being jacked up is decreased.

A cutting disc for a machine for harvesting stem-like plants includes a number of elements which together can be attached or are attached to a bracket forming a circular ring with an outer cutting edge. At least one of the elements is attachable to the bracket in a first position, in which a first edge of the element forms the outer cutting edge, and in a second position, in which a second edge of the element forms the outer cutting edge. No matter whether the element is in the first of second position, a circular cutting edge is made up.

A stalk roll assembly for header of a combine harvester. The assembly includes first and second stalk rolls spaced laterally with respect to one another and rotating in opposite directions. Each stalk roll includes a frusto-conical nose and a cylindrical body. The cylindrical body includes a plurality of radially extending flutes. The nose includes a pair of helical flights. The plurality of flutes includes at least one cutting flute having a straight edge and a plurality of puncturing flutes with teeth. The stalk rolls are laterally offset a distance that permits the tips of the flutes to laterally overlap and the teeth of the puncturing flutes are longitudinally offset so the tips of the teeth are received between with the valleys of the teeth of the other stalk roll.

A stalk roller assembly for an agricultural system includes a stalk roller having a hollow shaft. The hollow shaft has a first end having a first shape, such that the first end engages a guide element. Furthermore, the hollow shaft has a second end having a second shape that engages a drive shaft, such that the first shape is different than the second shape. In addition, the hollow shaft is formed from a single piece of material.

A pair of reel mower cutting unit steering limiters including a pair of pivoting members that may be independently pivoted between an engaged position providing a full range of steering of a reel mower cutting unit in a first direction on a vertical yaw axis, and a disengaged position reducing the steering of the reel mower cutting unit in the first direction. The maximum steering angle may be independently adjustable in each direction.
